'pconnect' : 'connect';$this->expire = isset($options['expire'])?$options['expire']:C('DATA_CACHE_TIME');$this->handler = new Memcache;$this->connected = $options['timeout'] === false ?$this->handler->$func($options['host'], $options['port']) :$this->handler->$func($options['host'], $options['port'], $options['timeout']); 不过不要紧,稍微修改下就行了,即 if(empty($options)) { $options = array ( 'timeout' => false, 'persistent' => false, 'servers'=>array( array('ip'=>'127.0.0.1','port'=>11211), array('ip'=>'127.0.0.1','port'=>11212), array('ip'=>'202.116.32.4','port'=>11211), ), );}//分布式处理函数$func="addServer";$this->expire = isset($options['expire'])?$options['expire']:C('DATA_CACHE_TIME');$this->handler = new Memcache;if($options['timeout']===false){ foreach($options['servers'] as $server) { $this->handler->$func($server['ip'],$server['port']); }} 闲来无事,于是就在本机上启动了两个MemCache服务器,顺手编写了一段简单的监控代码(隔一段时间自动刷新一次),进行测试。如果发现服务器运行不正常,则使用PhpMailer自动发送一封Email到管理员邮箱。测试结果表明,两台Memcache服务器均工作正常,而另外一台虚假的服务器当然是无法连接到的。
